[QUOTE=Squawk7700;10849927]F.a.r.k I got dizzy just watching that, let alone being in it. That pilot must have been a figure skater in a past life. Would love to hear from a spinner on here eg djpil if his technique should have got results.[ ..../QUOTE]That is an extract from a longer video, the actions prior to this are interesting and relevant to the question posed by Squawk. As already mentioned, there has been some discussion with the pilot in this video elsewhere. May be of interest to some but irrelevant to the question as to whether it complies with the ASTM requirements for a type not approved for spinning.
